QUnit Testing Interview Questions And Answers

QUnit is a unit testing framework for JavaScript programming language. It is important in the test driven development, and is used by jQuery, jQuery UI, and jQuery Mobile projects. QUnit is capable of testing any generic JavaScript codebase.

QUnit promotes the idea of "first testing then coding", which emphasizes on setting up the test data for a piece of code, which can be tested first and then implemented. This approach is like "test a little, code a little, test a little, code a little..." which increases the programmer’s productivity and the stability of program code reducing the programmer’s stress and the time spent on debugging.

Callbacks: When integrating QUnit into other tools such as CI servers, these callbacks can be used as an API to read the test results.

Configuration and Utilities: These methods and properties are used as utility helpers and to configure QUnit. For example, to adjust the runtime behavior directly, extend the QUnit API via custom assertions, etc.

QUnit tests provide good support for asynchronous testing. These types of tests are often needed for UI functional tests, for example if you have to wait until rendering is done, animations are complete, or a backend call returns. In addition, a QUnit test page can be executed standalone in the browser without the need of an additional "tool". This makes the creation and execution of single QUnit tests much easier. Finally, QUnit is closely related to jQuery, which is also a fundamental part of SAPUI5.
